Abstract: A belt device includes a plurality of support rotators, a belt, a cleaner, and a rotator inclination unit. The belt is looped around the plurality of support rotators and moves according to rotation of the plurality of support rotators. The cleaner contacts a surface of the belt to remove foreign substances. The rotator inclination unit inclines an inclined support rotator that is at least one of the plurality of support rotators. The cleaner is disposed in contact with a portion of the belt stretched taut between the inclined support rotator and another support rotator. A pushing amount of the cleaner relative to the belt varies according to inclination of the inclined support rotator and is smallest in a state in which the inclined support rotator is not inclined by the rotator inclination unit.

Abstract: A belt device includes a plurality of support rotators, a belt, a rotator inclination unit, a belt tension adjuster, and a descent stopper. The belt is looped around the plurality of support rotators and rotated by rotation of the plurality support rotators. The rotator inclination unit inclines a rotation axis of a first support rotator of the plurality of support rotators relative to a rotation axis of another support rotator of the plurality of support rotators that is different from the first support rotator. The belt tension adjuster adjusts tension of the belt, and the descent stopper prevents the first support rotator from descending.
